Description

Technical Field

[0001] The present invention relates to the technical field of underground engineering construction, and particularly relates to a vertical rotation device and method for a steel reinforcement cage. Background Art

[0002] With the continuous advancement of infrastructure construction such as rail transit, tunnels, and underground integrated pipe galleries, the engineering application volume of ultra-deep diaphragm walls has increased significantly. As the main structure of the diaphragm wall, the super-long and overweight steel reinforcement cage has a high-risk construction process throughout the whole process.

[0003] Currently, the "double-crane lifting" process is generally adopted for the construction process of most steel reinforcement cages. However, for the most typical flexible structure system of the steel reinforcement cage, the stability during the lifting process is affected by multiple factors such as the performance of the crane, the reinforcement method of the steel reinforcement cage, the surrounding construction environment, and the precision of collaborative operation, and it is prone to deformation, disassembly, and even overturning. In addition, to ensure the safety of lifting, redundant reinforcement measures such as adding longitudinal and transverse steel trusses are usually adopted. However, when the steel reinforcement cage is lowered into the trench, such temporary reinforcement bars lose their function, resulting in waste of steel and increased construction costs.

It can be understood that the specific embodiments described herein are only for explaining the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only the parts related to the present invention rather than all the structures are shown in the drawings.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0053] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation manners.

[0054] Such as Figures 1 to 5As shown in the figure, this embodiment provides a vertical rotation device for a steel reinforcement cage, which includes a guiding structure 1, a supporting structure 2, and a lifting structure 3. Among them, the guiding structure 1 abuts against the ground; the supporting structure 2 includes a supporting platform 21, and the lifting structure 3 includes a first hoist 31, a lifting assembly 32, and a second hoist 33. The supporting platform 21 is used to carry the steel reinforcement cage 100 to be lifted. The first end of the supporting platform 21 is slidably arranged on the guiding structure 1, and the second end is hung on the hook part of the first hoist 31. Under the lifting action of the first hoist 31, the steel reinforcement cage 100 can be lifted and tilted synchronously with the supporting platform 21 to ensure the structural stability of the steel reinforcement cage 100 during the process of rotating from vertical to straight, effectively avoiding deformation or damage of the steel reinforcement cage 100.

[0055] The lifting assembly 32 includes a connecting mechanism 321 and a plurality of steel crossbeams 322 arranged at intervals. The connecting mechanism 321 is hung on the hook part of the second hoist 33. Each steel crossbeam 322 passes through the steel reinforcement cage 100 and is connected to the connecting mechanism 321. At the same time, one end of the steel crossbeam 322 extending out of the steel reinforcement cage 100 is inserted into the supporting platform 21 to ensure the stability of the steel reinforcement cage 100 during the process of tilting from the horizontal state to the vertical state and prevent the steel reinforcement cage 100 from slipping off the supporting platform 21. At the same time, with the setting of the lifting assembly 32, the single steel bars of the steel reinforcement cage 100 are stably abutted against the plane of the steel crossbeam 322, and there is no need to additionally set hanging points and reinforcing bars, which not only ensures the stability of the steel reinforcement cage 100 during the hoisting, transferring and lowering processes, but also can effectively improve the construction efficiency and save construction costs.

[0056] In addition, when the steel reinforcement cage 100 is lowered to the set position in the drilling hole, a plurality of steel crossbeams 322 abut against the ground at the entrance of the drilling hole and serve as a temporary resting beam to ensure the stability of the placement of the steel reinforcement cage 100 and greatly improve the construction efficiency.

[0057] Specifically, in this embodiment, the supporting platform 21 is composed of a plurality of standardized modules to form a frame structure, and the adjacent modules are connected by a standardized quick-connection method. During the actual application process, the modules can be quickly disassembled or spliced according to the size of the steel reinforcement cage 100, and the length and width of the supporting platform 21 can be flexibly adjusted to be applicable to steel reinforcement cages 100 of different size specifications, effectively shortening the construction period and improving the reuse rate of the device, with good economy.

[0058] Exemplarily, both the first hoist 31 and the second hoist 33 are commonly used crawler machines in the art, and their specific structures and principles refer to the prior art and will not be elaborated here. The maximum lifting weight of the first hoist 31 and the second hoist 33 can be set as required according to the actual weights of the supporting platform 21 and the steel reinforcement cage 100, and no specific limitation is made here.

[0059] Optionally, an anti-slip structure is provided on the steel spreader 322, and the steel reinforcement cage 100 abuts against the anti-slip structure. The anti-slip structure is an anti-slip pad provided on the side of the steel spreader 322 facing the steel reinforcement cage 100, such as a rubber pad, etc.; alternatively, the anti-slip structure is an anti-slip protrusion provided on the side of the steel spreader 322 facing the steel reinforcement cage 100. The anti-slip protrusion can be a dot-shaped protrusion or a protrusion with a pattern of any shape, as long as it can increase the contact friction between the steel reinforcement cage 100 and the steel spreader 322 and improve the stability of the steel reinforcement cage 100 abutting against the steel spreader 322. Its specific form refers to the prior art and is not specifically limited in this embodiment.

[0060] Optionally, referring to Figure 1 , a first baffle 11 is provided at one end of the guiding structure 1, and a second baffle 12 is provided at the other end. When the first crane 31 lifts the support platform 21 and the steel reinforcement cage 100 from the horizontal state to the vertical state, the second baffle 12 is used to stop the first end of the support platform 21 to ensure that the support platform 21 does not slide along the guiding structure 1 after being lifted to the vertical state. The setting of the first baffle 11 is to limit the second end of the support structure 2 when the guiding structure 1 is changed from the vertical state to the horizontal state, prevent the support platform 21 from slipping off the guiding structure 1, and ensure the smooth progress of the next lifting operation.

[0061] Optionally, continuing to refer to Figure 1 , a plurality of support brackets 4 are spaced apart on the guiding structure 1 and / or on the ground. The support brackets 4 are used to carry the support platform 21 that has not been lifted, so as to ensure the levelness of the support platform 21, and further ensure the levelness of the steel reinforcement cage 100. Operators can directly tie the steel reinforcement cage 100 on the support platform 21 to avoid deformation and damage of the steel reinforcement cage 100 during the process of being transferred to the support platform 21. Specifically, the number of the support brackets 4 can be set as required and is not specifically limited here. In addition, the support brackets 4 are also existing devices and will not be elaborated here.

[0062] Optionally, the support structure 2 further includes a moving member 22. The moving member 22 is provided at the first end of the support platform 21 and is slidably provided on the guiding structure 1. The above setting can improve the smoothness of the support platform 21 sliding along the guiding structure 1, and thus improve the operation efficiency. Specifically, in this embodiment, the moving member 22 is a trolley, and moving wheels are provided on the bottom side of the trolley. The moving wheels are slidably provided on the guiding structure 1; in other embodiments, the moving member 22 can also be directly set as a moving wheel, as long as it can improve the smoothness of the support platform 21 sliding along the guiding structure 1.

[0063] Further, the guiding structure 1 includes a plurality of guide rails 13 arranged at intervals. A plurality of moving members 22 are arranged at intervals at the first end of the support platform 21, and the moving members 22 are slidably arranged on the guide rails 13. The arrangement of the guide rails 13 can provide a guiding effect for the sliding of the support platform 21, ensuring the accuracy of the sliding direction of the first end of the support platform 21.

[0064] Exemplarily, in this embodiment, four guide rails 13 are provided and two moving members 22 are provided; in other embodiments, the numbers of the guide rails 13 and the moving members 22 can be set as required and are not specifically limited herein.

[0065] Optionally, as Figure 5 shown, the connecting mechanism 321 includes a main beam 3211, a hoisting rope 3212 and a plurality of connecting members 3213. A plurality of steel spreaders 322 correspond to the plurality of connecting members 3213 one by one, and the connecting members 3213 are connected between the steel spreaders 322 and the main beam 3211, that is, the steel spreaders 322 are connected to the main beam 3211 through the connecting members 3213. The hoisting rope 3212 is arranged on the main beam 3211 and is hooked on the hooking part of the second hoisting machine 33. The above arrangement can disperse the weight of the steel reinforcement cage 100, optimize the load distribution of the main beam 3211, avoid excessive load on a single connecting member 3213 or a local part of the main beam 3211, and reduce the risk of structural deformation or fracture caused by stress concentration.

[0066] Further, with continued reference to Figure 5 , the connecting member 3213 includes two connecting ropes 3214. The two connecting ropes 3214 are arranged at intervals at both ends of the steel spreader 322 and are arranged on both sides of the steel reinforcement cage 100. The arrangement of the above two connecting ropes 3214 cooperates with the arrangement of the plurality of steel spreaders 322, which can restrain the posture of the steel reinforcement cage 100 during hoisting and prevent the steel reinforcement cage 100 from twisting or swinging.

[0067] Specifically, in this embodiment, as Figure 5 shown, a connecting plate 3215 is arranged between the connecting member 3213 and the main beam 3211. The connecting plate 3215 is triangular, and the ends of the two connecting ropes 3214 away from the steel spreader 322 are connected to the connecting plate 3215. With the above arrangement, during the transfer and lowering of the steel reinforcement cage 100, the connecting ropes 3214 are always in a vertical state. The connecting ropes 3214 mainly bear the vertical tension and there is no separation in the horizontal direction, avoiding the swaying of the second hoisting machine caused by the lateral tension and ensuring the safety during the operation process.

[0068] Optionally, as Figure 1As shown, the lifting structure 3 further includes a winding mechanism 34 and a traction rope 35. The winding mechanism 34 is arranged on the guiding structure 1. One end of the traction rope 35 is connected to the first end of the support platform 21, and the other end is wound on the winding mechanism 34. With the above arrangement, when the first end of the support platform 21 slides along the guiding structure 1 under the tipping action of the first crane 31, the winding mechanism 34 synchronously winds the traction rope 35 to provide a horizontal traction force to the first end of the support platform 21, so that the support platform 21 forms a coupled motion of vertical lifting and horizontal traction, further improving the smoothness during the vertical rotation and tipping process of the support platform 21 and the steel reinforcement cage 100.

[0069] Specifically, in this embodiment, two winding mechanisms 34 are provided; in other embodiments, the specific number of the winding mechanisms 34 can be set as required and will not be specifically limited here.

[0070] Exemplarily, the winding mechanism 34 is a winch commonly used in the art, and its specific structure and principle refer to the prior art and will not be elaborated here.

[0071] In addition, referring to Figures 6 to 14 this embodiment also provides a method for vertically rotating a steel reinforcement cage, which is applied to the above-mentioned steel reinforcement cage vertical rotation device and includes the following steps:

[0072] S1: The steel reinforcement cage 100 is placed on the support platform 21, and the end of the steel crossbar 322 extending out of the steel reinforcement cage 100 is inserted into the support platform 21; the second end of the support platform 21 is hung on the hook part of the first crane 31, and the connecting mechanism 321 is hung on the hook part of the second crane 33.

[0073] In the above steps, specifically in this embodiment, according to the size of the steel reinforcement cage 100, the standardized modules of the support platform 21 are assembled to complete the construction of the support platform 21. The steel reinforcement cage 100 is placed on the support platform 21, and the steel crossbar 322 is passed through the steel reinforcement cage 100 and one end is inserted into the support platform 21 to ensure the stability during the tipping process of the steel reinforcement cage 100.

[0074] The second end of the support platform 21 is hung on the hook part of the first crane 31, and the connecting mechanism 321 is hung on the hook part of the second crane 33.

[0075] Specifically, the steel reinforcement cage 100 can be directly tied on the support platform 21, or the steel reinforcement cage 100 can be tied at other positions and then transferred to the support platform 21.

[0076] S2: The first crane 31 lifts upward, driving the first end of the support platform 21 to slide along the guiding structure 1;

[0077] In the above steps, specifically in this embodiment, the first crane 31 hoists upward, driving the second end of the support platform 21 to rise, and the moving member 22 provided at the second end of the support platform 21 slides along the guide rail 13. At the same time, the winding mechanism 34 provides a horizontal pulling force to the first end of the support platform 21 through the winding traction rope 35, so that the support platform 21 and the steel bar holes are smoothly and stably lifted from the horizontal state to the vertical state.

[0078] More specifically, during the process of the support platform 21 being lifted, a total station is used to real-time locate the spatial positions of the support platform 21 and the steel bar cage 100. Combining the force data feedback by the pressure sensor and the displacement data feedback by the position sensor, the winding and unwinding of the traction rope 35 by the winding mechanism 34 and the hoisting height of the first crane 31 are adjusted. Among them, the total station, the pressure sensor and the position sensor are all existing devices, and their specific structures and principles refer to the prior art, which will not be elaborated here.

[0079] S3: When the support platform 21 is hoisted perpendicular to the ground, the second crane 33 moves horizontally to separate the steel bar cage 100 from the support platform 21;

[0080] In the above steps, specifically in this embodiment, during the vertical rotation process of the support platform 21, the hook part of the second crane 33 only moves synchronously with the steel bar cage 100 as a following component and does not bear the traction force. When the support platform 21 is lifted to be perpendicular to the ground, the second baffle 12 can stop the support platform 21 from continuing to slide along the guiding structure 1 to ensure the vertical state of the support platform 21. After the vertical rotation of the support platform 21 is completed, the second crane 33 is started to drive the steel bar cage 100 to move horizontally, so that the steel bar cage 100 is smoothly separated from the support platform 21.

[0081] More specifically, during the process of separating the steel bar cage 100 from the support platform 21, a tension sensor and an angle sensor are used to real-time monitor the force condition and the specific attitude change of the steel bar cage 100. Among them, the tension sensor and the angle sensor are all existing devices, and their specific structures and principles refer to the prior art, which will not be elaborated here.

[0082] S4: The second crane 33 transports the steel bar cage 100 to the drilling position, then lowers the steel bar cage 100 into the drill hole, and makes the steel crossbar 322 abut against the ground.

[0083] In the above steps, specifically in this embodiment, the second crane 33 transports the steel bar cage 100 to the drilling position, then lowers the steel bar cage 100 into the drill hole, and makes the steel crossbar 322 abut against the ground, that is, the steel crossbar 322 acts as a temporary support beam to provide a stable support and positioning function for the steel bar cage 100.

[0084] Meanwhile, the hook of the first crane 31 is lowered, and the winding mechanism 34 gradually releases the towing rope 35, driving the support platform 21 to change from the vertical state to the horizontal state to facilitate the next vertical rotation of the steel reinforcement cage 100.

[0085] Specifically, during the lowering process of the steel reinforcement cage 100, the ultrasonic sensor and the laser rangefinder are used to monitor the distance between the steel reinforcement cage 100 and the hole wall in real time, and the measured data is fed back to the control room. The operator accurately controls the lowering angle and position of the second crane 33 based on the feedback data to ensure that the steel reinforcement cage 100 is accurately lowered according to the design requirements. Among them, both the ultrasonic sensor and the laser rangefinder are existing devices, and their specific structures and principles refer to the existing technology and will not be elaborated here.

[0086] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
